Hi!
I read a lot about the excellent Jitter Recipe 36 TinyVideo, and jit.expr but after many failed attempts, I have to give up. I understand tutorial Demystifying Expressions in Jitter, and plunges into "jit.expr and shatter" topic, but I think I am too stupid for that… Now I am looking for another way to shatter the image consist of 16 per 9 squares. I want to randomly swap their place with a frequency of about 50 milliseconds. Do you have an idea for a simpler solution than jit.expr? As always I am extremely grateful and really appreciate your knowledge. I upload the picture in which I would like to shatter cells.

The mesh.shatter example can be modified to perform this task. You basically need to change the original shape to a plane and pipe in a texture coordinate matrix through the jit.gen object that calculates the shatter geometry. I was curious at how this would look, so I tried it myself:

wow, thanks for your work! :)
maybe i didnt explain my problem well. I am dealing only with changing the coordinates of texture, leaving the position. maybe i will post my patch, showing what i have already done.

in my patch i want to get rid of the black border around the squares, and dont change the size of the thumbnails from the 169.jpg image. I would like only to random the position of each cell with the others. I dont know if i explained it well, you have to forgive me (:

hi! i found, that there is some problem with chosing the texture. If i am right i should be able to chose the texture, feeding texcoord inlet with float matrix, from 0 to 1. the texture change however i am loosing a lots of source textures (the small ones from jpg) – i ve got about 23 textures, from 16*9 grid of textures. i was trying to analyze the whole patch, but i am getting lost everytime.
thanks for help!
